Sexual desires

So I keep thinking about this and I am truly worried. So I’m a 18 year old virgin and idk if it’s because of it that I don’t feel sexually attractive towards someone. Like at times when I get horny I think about having sex with guys. But at times I like lesbian porn because I find it more interesting. I like the thought of having sex with a women but that’s it. Idk I feel like there’s something wrong with me cause I don’t feel sexually attractive to a guy I met. But I like guys so idk what to think. It’s stressing me over 🤦🏻‍♀️ please any help!
